org.uma.evolver.parameter.factory.BinaryParameterFactory

All Implemented Interfaces:

ParameterFactory<org.uma.jmetal.solution.binarysolution.BinarySolution>

public class BinaryParameterFactory
extends Object
implements ParameterFactory<org.uma.jmetal.solution.binarysolution.BinarySolution>

Factory class for creating and configuring categorical parameters specific to evolutionary algorithms that operate on BinarySolution individuals. This factory implements the ParameterFactory interface to provide type-safe creation of various algorithm components and their parameters.

The factory supports the creation of parameters for different components including:

• Variation operators (crossover, mutation)
• Selection mechanisms
• Archiving strategies
• Solution initialization methods
• Density estimators
• And other algorithm-specific parameters

This implementation is specifically designed for algorithms working with binary-encoded solutions and provides appropriate parameter types that are compatible with the BinarySolution interface.

Method Details

createParameter

public CategoricalParameter createParameter(String parameterName,
 List<String> values)

Creates and returns a specific CategoricalParameter instance based on the provided parameter name. This factory method centralizes the creation of all parameter types used in evolutionary algorithms that operate on binary-encoded solutions.

The following parameter types are supported:

any other value	CategoricalParameter	Basic categorical parameter with the given name

Specified by:

createParameter in interface ParameterFactory<org.uma.jmetal.solution.binarysolution.BinarySolution>

Parameters:

parameterName - the name of the parameter to create (case-sensitive)

values - the list of possible string values for the parameter (must not be null or empty)

Returns:

an instance of CategoricalParameter corresponding to the specified parameter name

Throws:

IllegalArgumentException - if the values list is null or empty
